As of release 1:6.0.0r1-1 fonts-droid-fallback does not install DroidSansFallback.ttf to fontconfig monitored path. This is meant to fix bug #762296 (http://bugs.debian.org/762296) as this file share the same name ("Droid Sans Fallback") with DroidSansFallback.ttf showing up before DroidSansFallbackFull.ttf while the latter is the preferred font for rendering Chinese content in some installations. As a consequence, the offending file is moved in /usr/share/fonts-droid/truetype and therefore not automatically seen by fontconfig. -- Vasudev Kamath , Sun, 13 Dec 2015 14:16:03 +0530
